Shortwave Radiogram, 24-27 September 2020: Do you see a pattern here?

 

Perhaps because of equinox propagation, reception of Shortwave Radiogram
has been difficult lately in some parts of the world. Listeners in the
eastern half of North America have been especially affected, with many
of our frequencies (15770 for example) “going long.” To compensate for
any reception difficulties this weekend, we will include some MFSK16
text – slow but robust – in addition to our usual MFSK32 and MFSK64.

We will also transmit this black-and-white test pattern in all three
modes (MFSK16, 32 and 64) so that you can observe the differences in
resolution among the MFSK modes. The transmission time is about the same
for all three …

Videos of last weekend’s Shortwave Radiogram (program 170) are provided by Scott in Ontario (Friday 1300 UTC), 2010DFS in Japan (Sunday 0800 UTC on 5850 kHz), Ralf in Germany and Frigid RF in Virginia (both Sunday 2330 UTC). The audio archive is maintained by Mark in the UK. Analysis is prepared by Roger in Germany.

This weekend’s show is in MFSK16, MFSK32, and MFSK64, with eleven MFSK images.

Here is the lineup for Shortwave Radiogram, program 171, 24-27 September 2020, in MFSK modes as noted:

1:41  MFSK32: Program preview
2:53  MFSK16: Test pattern*
4:48  Deep-space observation from lunar orbit

the broadcast. It’s transmitted on WRMI, Thursdays at 0200-0300 UTC on
5850 kHz (Wednesday evening in the Americas) and a new time also on

New York and Pennsylvania NBEMS nets. Most weekends, as
KD9XB, I check in to the New York NBEMS (Narrow Band Emergency
Messaging Software) net Saturday at 1200 UTC on 3584 kHz USB, and the
Pennsylvania NBEMS net Sunday at 1200 UTC on 3583 kHz USB (with
out-of-state check-ins now starting at 1130 UTC). Check-ins are usually
in Thor 22, and messages are in MFSK32. Messages generally use the Flmsg
add-on to Fldigi. If you are a radio amateur in eastern North America,
feel free to check in. Outside the region, use an SDR in the eastern USA
to tune in and decode. You do not need Flmsg to check in, and most of
the messages can be read without Flmsg. If you can decode the net, send
me an email to radiogram@verizon.net , or tweet to @SWRadiogram , and I
will let them know you are tuned in. USEast NBEMS Net: Please also note the USEast NBEMS Net, Wednesdays 2300 UTC (7 pm EDT) on 3536 kHz USB.
